the best attack ad on romney is mitt romney. to pick up on michael and michelle's point, what is romney going to come with in the campaign to have a good showing? he can't talk about taxes with tacks being the lowest they have been in 50 years. he can't talk about medicaid and medicare because their policies are unpopular. he can't talk about foreign policy, he doesn't have anything. the only thing he can argue is that obama has not been a good steward of the economy, but as we know, obama has a very good answer to that. and that's on offense. then you think about what he has to do on defense. he's going to be on the defense on the 47%. he's going to be on defense on his tax question. i mean, this is a guy who doesn't have very much to work with at this point. so it's hard for me to see, even if he doesn't make a major gaffe, which he does on a weekly basis, even if he doesn't, what ammunition does he have to actually have a good showing? >> i'm told there are examples of elections turning on debates, president bush for example
